Patent GB-307784-A (GB)
Abstract: 307,784. Kemikal, Inc., (Assignees of Mellanoff, I. S.). March 13, 1928, [convention date]. Salts of oxalic, formic, acetic, and fatty acids. -Alkali or alkaline earth salts of oxalic acid and saturated monobasic fatty acids are obtained by heating carbohydrates such as sawdust, wood, moss, paper pulp, paper, rags, straw, or other vegetable matter or waste material containing carbohydrates, or substances in which the carbohydrate molecule has been altered or changed, with alkali in the presence of a heavy hydrocarbon. which acts as a catalyst. Air may be supplied to the mixture, preferably by forcing it in streams through the material, a convenient method being to inject it through orifices arranged at or near the bottom of the vessel containing the mass. In an example, a pulp made from waste newspapers is added to a solution of sodium hydroxide and the mixture gradually heated to 200‹ C., air being supplied as above. The heating and aeration are continued until most of the water is eliminated, some sodium oxalate and sodium salts of the other aliphatic acids being formed during this part of the process. A small proportion of a heavy hydrocarbon such as paraffin is then added, and the process continued at 210‹ C. for about 4 hours. The air is shut off, and the temperature allowed to tall during 6 nours to about 150‹ C. '1'he mass is then allowed to cool, after which the salts formed may be extracted and treated by known methods for the formation of the corresponding acids. The Specification as open to inspection under Sect. 91 (3) (a) is not restricted to the production of salts of oxalic acid and monobasic fatty acids, but comprises the production of oxygencontaining compounds of the aliphatic series in general, and in particular oi aliphatic acids such as oxalic acid, formic acid, and acetic acid. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 160,467.

Abstract: 520,595. Stapling filaments. TAYLOR, W. I., and WOODRUFF, A. H. Oct. 26, 1938, No. 30962. [Class 120 (iii)] Staple fibre is obtained by cutting continuous filaments in dry condition and then carrying the fibre by suction through a conduit to a transverse chamber of subsantially larger cross section than the conduit, and collecting it from the chamber. A bundle 1 of dry continuous filaments proceeds through the nip rolls 2 and funnel 3 to the cutting machine 4, from which the cut filaments 'pass through the conduit 8 to its forked ends 10. These ends are connected to ends of horizontal chambers 9, and the other ends of the chambers are connected to pipes 11 which merge to form the inlet of the suction pump 12. The valve 14, with its counterweighted handle 15, and the dampers 16 are set so that suction'is applied to one chamber, and the fibres are sucked into it with considerable velocity. The change of direction they undergo gives them a swirling motion and they are finally stopped by the screen 17. They can be inspected through the windows 18 and when desired the other chamber can be thrown into action. The fibres can be removed from the first chamber after the cover 19 has been lifted. The Provisional Specification states that the suction may be applied through a rotary perforated cage fitted with a mask, and continuous removal is effected by means of a lattice.

[Also in Division C2] In a process for oxidising saturated hydrocarbons (see Division C2), part of the liquid phase is continuously withdrawn and reinjected as stirring liquid from at least one injection point with a direction which imparts rotational movement to the liquid phase. The charge is introduced through duct 14 into vertical tower 1 which has a conical bottom terminating with outlet duct 2 for liquid products, duct 3, conveying an O 2 -containing gas, e.g. air, preferably terminates in a perforated ring distributor the holes of which are oriented towards the bottom of 1 (or to avoid the ring, the gas may be injected through holes in the conical base by a device not shown), the liquid outflow from 2 is aspirated by pump P and forced through four diametrically opposed pairs of stirring ducts 4, 5, 6, 7 which may be narrowed to injection nozzles and which are oriented tangentially to the column walls so as to wash them. Alternatively, these may be used 6 stirring ducts conveying the liquid at different levels and opening into 1 at angular intervals of 120‹ from each other. Duct 7 is preferably close to the liquid-gas interface 9 and at least the majority of the ducts are oriented to impart to the liquid as a whole a rotational movement in one direction about a vertical axis. Duct 10 is for evacuating residual gases and duct 11 conveys the liquid hydrocarbon for washing the gases into cup 12 from which liquid overflows onto the outside of upturned funnel 13, so that the escaping gases are scrubbed by a continuous screen of washing liquid.
